Pleasantly surprised at those prices! Free was better but it's not astronomical. I think they want to ensure everyone doesn't flip over to a car service which is something I'm considering too, especially if it includes a grocery stop.
We were sad to realize our final DME trip was in Sep 2019 and we didn't even know it at the time. We were supposed to go later this month but border closure had us changing our dates again.
I'm going to look into the above and find out their cancellation policies also.
